  52 C4::Reserves - Koha functions for dealing with reservation.

  54 =head1 SYNOPSIS
  55
  56   use C4::Reserves;
  57
  58 =head1 DESCRIPTION
  59
  60 This modules provides somes functions to deal with reservations.
  61
  62   Reserves are stored in reserves table.
  63   The following columns contains important values :
  64   - priority >0      : then the reserve is at 1st stage, and not yet affected to any item.
  65              =0      : then the reserve is being dealed
  66   - found : NULL       : means the patron requested the 1st available, and we haven't chosen the item
  67             T(ransit)  : the reserve is linked to an item but is in transit to the pickup branch
  68             W(aiting)  : the reserve is linked to an item, is at the pickup branch, and is waiting on the hold shelf
  69             F(inished) : the reserve has been completed, and is done
  70   - itemnumber : empty : the reserve is still unaffected to an item
  71                  filled: the reserve is attached to an item
  72   The complete workflow is :
  73   ==== 1st use case ====
  74   patron request a document, 1st available :                      P >0, F=NULL, I=NULL
  75   a library having it run "transfertodo", and clic on the list
  76          if there is no transfer to do, the reserve waiting
  77          patron can pick it up                                    P =0, F=W,    I=filled
  78          if there is a transfer to do, write in branchtransfer    P =0, F=T,    I=filled
  79            The pickup library receive the book, it check in       P =0, F=W,    I=filled
  80   The patron borrow the book                                      P =0, F=F,    I=filled
  81
  82   ==== 2nd use case ====
  83   patron requests a document, a given item,
  84     If pickup is holding branch                                   P =0, F=W,   I=filled
  85     If transfer needed, write in branchtransfer                   P =0, F=T,    I=filled
  86         The pickup library receive the book, it checks it in      P =0, F=W,    I=filled
  87   The patron borrow the book                                      P =0, F=F,    I=filled

 284 the C<all_dates> parameter can be included and set to a true value.
 285
 286 If the C<itemnumber> parameter is supplied, reserves must be targeted
 287 to that item or not targeted to any item at all; otherwise, they

1114
1115 C<$rank> specifies the effect of the change.  If C<$rank>

1117 request alone when changing its priority in the holds queue
1118 for a bib.
1119
1120 If C<$rank> is 'del', the hold request is cancelled.
1121
1122 If C<$rank> is an integer greater than zero, the priority of
1123 the request is set to that value.  Since priority != 0 means
1124 that the item is not waiting on the hold shelf, setting the
1125 priority to a non-zero value also sets the request's found
1126 status and waiting date to NULL.
1127
1128 The optional C<$itemnumber> parameter is used only when
1129 C<$rank> is a non-zero integer; if supplied, the itemnumber
1130 of the hold request is set accordingly; if omitted, the itemnumber
1131 is cleared.
1132
1133 B<FIXME:> Note that the forgoing can have the effect of causing
1134 item-level hold requests to turn into title-level requests.  This
1135 will be fixed once reserves has separate columns for requested
1136 itemnumber and supplying itemnumber.

1694 hold is set to supplied rank, and other holds for that bib are adjusted
1695 accordingly.  If the rank is "del", the hold is cancelled.  If no rank
1696 is supplied, all of the holds on that bib have their priority adjusted
1697 as if the second form had been used.
1698
1699 In the second form, where a biblionumber is passed, the holds on that
1700 bib (that are not captured) are sorted in order of increasing priority,
1701 then have reserves.priority set so that the first non-captured hold
1702 has its priority set to 1, the second non-captured hold has its priority
1703 set to 2, and so forth.
1704
1705 In both cases, holds that have the lowestPriority flag on are have their
1706 priority adjusted to ensure that they remain at the end of the line.
